The ECS M920 motherboard from ECS Elitegroup is the ECS Elitegroup iteration of the M920 motherboard chipset from Intel Technologies. First released in 2000, these boards were produced for a very short period of time because of the brief nature of the CPU socket type being used by Intel at the time. This makes the board type hard to find and the number of CPUs that are compatible with the board are limited to a select few.
Central Processing Unit
The ECS M920 motherboard supports the "Willamette" Intel Pentium 4 processors designed for Socket 423. These were produced for only a short time before Intel moved the Pentium 4 line to the new, more advanced Socket 478--and eventually Socket 775--to better compete with AMD's Athlon XP line. This means that the ECS M920 only supports CPUs that work between 1.4 GHz and 2 GHz.
Hard Drive
Because both the optical drives and hard drives supported by the ECS M920 are IDE devices, the ECS M920 can support between one and three optical drives and a single hard drive. On the flip side, your motherboard can also support up to three hard drives and a single optical drive. This is possible thanks to the two IDE channels on the motherboard, in addition to the single floppy disk controller that is set aside exclusively for your floppy drive.
Expansion Slots
The ECS M920 has several expansion ports for both RAM and expansion cards. The motherboard features four different DIMM slots, two for 184-pin DDR RAM and two for 168-pin SDRAM slots. The motherboard also supports up to 1GB of RAM, though the DDR and SDRAM cannot be mixed. In addition to the RAM slots, the board features one CNR slot, one 4x AGO slot and four PCI slots for various expansion cards.
